Regional brain levels of the drugs as well as monoamine neurotransmitters and some of their major acidic metabolites were determined. Amphetamine produced depletions of dopamine in the striatum after at least 3 days of treatment but not in the nucleus accumbens or olfactory tubercle, even after 14 days of treatment. In contrast, the two ring-substituted amphetamine analogues increased levels of the

BACKGROUND: Amphetamine and amphetamine-type stimulants are powerful physical and psychostimulants; they are phenethylamine derivatives. The use of amphetamines can be either medicinal or illicit. Several amphetamines have been redesigned into illegal drugs of potent properties, also known as research chemicals and designer drugs. Hence, they are named novel (new) psychoactive substances (NPS).MATERIALS & METHODS: This study is a hybrid study of; data crunching and retrospective analysis of a trends database (1), and a systematic review of literature in relation to the amphetamines-induced

Abstract Background: Immunoassay-based screening for amphetamines has a variable positive predictive value (PPV) for detecting amphetamine abuse. The lack of immunoassay specificity necessitates confirmatory testing by gas chromatography–mass spectrometry (GC/MS), but the technical complexity and expense of GC/MS limit its availability. Physicians may make decisions regarding patient disposition based on unverified results. In this study we assessed the utility of using dose–response properties to distinguish urine samples containing amphetamines from samples containing cross-immunoreactive sp

Introduction: Attention-deficit-hyperactivity disorder (ADHD) affects a substantial portion of the global population, influencing cognitive and behavioral function. Current treatments often involve stimulant medications like amphetamines, which are controlled substances due to their addiction potential. Non-stimulant options, such as atomoxetine, are typically considered secondary therapies. This study examines the relationship between ADHD medication use and the subsequent development of psychoactive, stimulant, and cocaine-related substance use disorders.

This has been an argument for using amphetamine-induced psychosis as a model for primary psychotic disorders. To distinguish the two types of psychosis on the basis of acute symptoms is difficult.

Only fluorescence intensity need be measured because the emission of non-protein-bound fluorescein-labeled amphetamine is preferentially quenched by detergent micelles.

The plasmalemmal monoamine transporters for dopamine, norepinephrine, and serotonin (SERT) are targets for amphetamines. In vivo, amphetamines elicit most, if not all, of their actions by triggering monoamine efflux. This is thought to be accomplished by an amphetamine-induced switch from the forward-transport to the substrate-exchange mode. The mechanism underlying this switch has remained elusive; available kinetic models posit that substrates and cosubstrate Na+ ions bind either in a random or in a sequential order. Neither can account for all reported experimental observations. We used ele

The illicit production and distribution of amphetamines present significant challenges to public health and law enforcement, particularly in Europe, where these substances dominate the stimulant market. This study aimed to profile amphetamines consumed within a Polish community by employing gas chromatography–mass spectrometry (GC-MS) and chemometric techniques to analyze their chemical composition and associated impurities. The optimized GC-MS methodology facilitated the identification of synthesis markers, precursor origins, and distribution patterns. Impurity profiling provided critical ins

Introduction Urine Drug Screening (USD) is one of the most used techniques for drug testing. However, one of the main issues related to USD is the high frequency of cross-reactivity with other molecules. Amphetamines, because of their simple structures, are highly subjected to cross-reactivity with other molecules. Objectives Our aim was to investigate and characterize the role of psychopharmacological drugs in the occurrence of false-positive amphetamine drug screening, by performing an international pharmacovigilance study through the Food and Drug Administration Adverse Event Reporting Syst

The effects of systemic injections of amphetamine sulfate on the release of aspartic acid, glutamic acid, and glutamine were studied using a push–pull perfusion system in the conscious rat. Amphetamine produced a dose-related increase of the extracellular levels of aspartic acid and glutamic acid. The mean time effect of amphetamine was 40 min, followed by a recovery to baseline levels. The mean percentage increase in amino acids released by the highest dose of amphetamine (5 mg/kg) was as follows: Asp, 334.6%; Glu, 224.5%; and Gln, 317.6%. All these effects were blocked by the dopamine D1–D2

Suicide is an act of ending one's own life that is often associated with mental health disorders and life pressures. Amphetamines are classified as Class II psychotropic drugs that have a strong stimulant effect on the central nervous system, causing changes in behavior and mental activity, including hallucinations, thought disorders, and emotional changes.

Abstract Introduction Despite recent introduction of several FDA-approved treatments for narcolepsy, clinical management of narcolepsy type 2 (NT2) and idiopathic hypersomnia (IH) still relies heavily on treatment with modafinil and amphetamines. While modafinil has a strong recommendation for use in these disorders by the American Academy of Sleep Medicine, clinical trial evidence regarding efficacy of amphetamines is scarce. Methods We performed a 12-week, randomized, fully-blinded, non-inferiority trial to determine if amphetamine-dextroamphetamine was non-inferior to modafinil in people wi

Background: Amphetamines increase dopamine levels in mid-brain regions which, in turn, impact top-down executive function. Repeated exposure is linked to substance use disorders. Nonetheless, amphetamines are used to manage attention-deficit/hyperactivity disorder (ADHD) and eating-related disorders. In ADHD, amphetamines upregulate a system characterised by low dopaminergic tone, assisting to improve executive function. A similar process might be at play with eating disorders; however, the effect of amphetamine treatment on executive function in this case has not been thoroughly considered. M
